Specification of Letters Patent.

Application filed April 25, 1912. Serial No. 693,255.

To all whom it may concern:

Be it known that I, EDWIN H. WHITNEY, a citizen of the United States,residing -at Somerville, .in the county of Middlesex and State ofMassachusetts, have invented an Improvement in Automatic Machines for 7Making Paper Drinking-Cups, of which the the ends of the cup-bodies overupon the flanges of the bottom-pieces to insure the drel its edges willbe overlapped, and said.

edges adhesively secured.

The machlne'also lnvolves means to remove any surplus paste from thepasted joint of the cup-body; and also means to apply pressure upon thepasted joint to insure.

its adhesion.

The machine is also designed to cut bottom-pieces from a web of paperand to form flanges on said bottom-pieces and to thrust the flangedbottom-pieces into the open ends of the cup-bodies. v

The machine also involves means to crimp formation of a tightjoint.

Themachine is also desi ed to coat the completed cups with para n-w.axor some.

equivalent substance, and, as said parafiinwax is applied in liquidform, at a high 16111-1 perature, means are provided to cool the coatedcups, preparatory to ejecting them= from the machine; and the. machinealso involves means to eject them upon a moving conveyor.

The machine is essentially of a rotary type, in that thecutting-meansfor the bodyblanks and the cutting-means tor the bot-,torn-pieces are of a rotary type; and themandrels are borne byarotarymandrel- PPQ'rt by which the cup;b di formed and successively conv d tth bottoming;

device and coating-device and ejecting-de-' vice; and the sraying-devicesby which- 'pa r'aflin is appliej to the cups are borne bypasting-means.

a rotary-carrier. Thus there is provided an eizsy running, continuouslyoperating mac 11119.

It is designed that a cup-body shall be formed and its bottom-pieceinserted, and the cup coated and ejected during a cycle of operation ofthe mandrel-support.

-Referring to Figs. 1 to 12, a roll 10 of paper is supported by suitablebearings in drawn from said roll intermittingly by a pair of feed-rolls16, 17, secured to shafts '18, 19, respectively, journaled in bearingsin the frame 14. To intermittingly rotate said. feed rolls apower-driven belt 20, passes over a pulley 22, secured to a shaft 24,jour- *naled in bearings on the under. side of the '1 frame a mutilatedgear 25,'.is" secured to i said shaft 24, wh-ich meshes with a gear 26,mounted on a stub-shaft 27 arranged on the frame -14,'and said gear 26'mesheS gear 28, secured to the shaft 19, which shaft i? bears the lowerfeed-roll l7, and said ear 128 meshes with a like gear 29, secured tothe shaft 18, which bears the upperlfeed-roll 16."

-- The'parts are' so proportioned that the the cups herein tion andpartial section of the carrier for- ..the cylinder 42.

out and is also positively fed forward, with a frame14, andthe strip ofpaper 11, is

minating su length of strip drawn off by each intermittent movement issufficient for a single body- .piece to, be-cut therefrom. The strip isfed orward to a rotary punch and die which act to cut body-piecestherefrom, of suitable 7o shape to-form the bodies of the cups, and asdesigned to be produced have conically formed bodies said bodypieces aresector-shaped, see Fig. 5. The rotary punch and die are positively yetintermittingly driven, and, as here shown, the aforesaid gear 26 whichis'rotated intermittingly by the mutilated gear 25, also meshes with agear 40, secured to a shaft 41, journaled in the frame, and said shaftcarries a cylinden 42, having a sector-shaped recess or female dieformed on its pe riphery, and said gear 40, meshes with a gear '44,secured to a'shaft 45, and said shaft 45 carries a cylinder 46, havinga,- sector-shaped g punch, shaped to correspond to the die on Duringeach cycle of operation of the punch and die a single. body-piece 50, iscutthe surrounding portion of the strip, between horizontally arrangedplates 52 and I 54, until it reaches a freely rotatabledeflecting-cyliilder 55, over which the waste portion of the strip 56passes on its way to a pair'of feed-rolls 34, 35. The lowermostfeed-roll 34, is designed. to be positively driven and the upperfeed-roll 35 to be rotated bybfrictionalengagement withthe waste portionof the strip which is arranged between the two rolls, and, as hereshown, the positively driven gear 29, before referred to, meshes with anintermediate gear 30, mountedon a shaft 31, journaled .in'the frame, andsaid gear 30 meshes with a gear 32, secured to the shaft 33, to whichthe low- .ermost feed-roll 34 is secured. The upper most feed-roll 35 ismounted to rotate freely 'on a shaft 36, supported by. the frame.

the gear 29 is rotated intermittingly the lowermost feed-roll 34 willberotated intermittingly, so that the waste feed-rolls 34, 35, willberotated intermittingly and in unison with. the feed-rolls 16, 17. The.waste porare pushed forward by the strip between a pair ofguiding-plates, as the waste portion is being deflected, andbythe-deflecting-cylinder 55, coq'iperatipgiwith a stationary plate,arranged beneath it; Said stationary plate is here shown as an-extension or continuation of theplate 52, and, as shown in Fig. 2, saidplate is also. extended beneath the guiding-lplate58, its forwardedgeterstantially 'flush with the for- I ward end of said guiding-plate 58,so that blocks are slidably mounted in ways 91, and

the forward end portion of said plate 52 and the guiding-plate 58 formthe pair of guiding-plates just referred to. The bodypieces 50 are movedforward into enga ment with one ormore pairs of feed-r0 ls, two pairsbein here shown, as 59, 60,and 61, 62, they be ng arranged one inadvance of the other, but near together. The upper rolls 59 and 61 ofsaid two pairs of feedrolls are secured to, shafts 63, 64, journaled inbearings in the frame, and said shafts 63, 64, have securedto' themgears 66, 67, respectively, which mesh with an intermediate gear 68.'The gear 66 also meshes with a gear 69, secured to a shaft 72 on theframe, and said shaft bears a' sprocket-wheel 74, over which passes asprocket-chain 76, which also passes over a sprocket-wheel 7 8, securedto the continuously rotating shaft 24.

As the shaft 24 rotates the feed-rolls 59,

61, arepositively rotated, and by their frictional engagement withthebody-pieces 50, which are passin between said 'rolls, and theircompanion eed-rolls 60, 62, the latter feed-rolls are rotated. It isdesigned and intended to feed the body-pieces 50 forward in a circularpath, hence the feed-rolls 59, 60, and 61, 62, are made conical, and aresupported by the frame so as to extend toward a common center, as bestshown in Fig. 6, and the gears 66, 67, 68 and 69, are beveled to providefor such radial disposition of the rolls. As said feed-rolls areconically formed, in order to enable their bite to occupy a horizontalplane, the-shafts bearing them are inclined, see Fig. 2. The

first pair of rolls 59, 60, are arranged at such distance from thedeflecting-cylinder 55, as to engage the forward end of a body-piecejust before the rear end of said body-piece disengages thedeflecting-cylinder, so that the body-pieces are held positively whilepassing fromthe deflecting-cylinder to said ,rolls. After passingbetween the rolls 61,.

62, the body-piece 50, encounters 'the un'der side of an inclineddeflecting-plate 80, see

Fig. 8, and by it is bent downwardly to pass over an inclinedguiding-plate 81, and by said guiding-plate is directed beneath aplurality of conical yieldingly-supported rolls 82, 83,84, arranged in aslightly inclined plane. Said rolls 82, 83, 84, are mounted to rotatefreely on stub-shafts 86, 87, 88, re-

spectively, which project from blocks 90,.

toward the same common center as the conical feed-rolls before referredto, and said pressed downward by springs 92. To hold the body-piece inengagement with said rolls 82, 83, 84, and to move it along a movableelement is provided which is'- designed to move in a .plane beneath saidrolls, and as here' shown said movable'element. consists of a propellerof novel construction, having.

several blades which successively pass beneath said rolls as thepropeller is rotated. As the body piece 50 leaves the inclinedguiding-plate 81, it is engaged by one of the blades 94 of thepropeller, and by said blade is held in engagement successively with theseveral rolls 8 2, 83, 84, as said blade is moved about its axis, thebody-piece being thus supported above 'by' the spring-pressed rolls andbelow by the blade, and the bodypiece is moved forward by the positivelymoving blade. As here shown, the propeller blades 94 are pivotallymounted on radial arms 96, carried by a head 97, arranged at the upperend of a vertical spindle 98, which is supported 'atits upper end in aboss on the horizontal arm of an angle bracket 99, and its lower end ina step bearing 100.

The propeller is rotated continuously, and

as here shown, a bevel-gear 101 is secured to the spindle 98, whichmeshes with a bevelpinion 102, secured to a short shaft jour the gearingust set forth the propeller spindle 98, is caused to rotatecontinuously. The propeller-blades 94 are sector-shaped and arepivotally supported along one edge only to the radial arms. 'Pivotallysupporting the propeller-blades on the radial arms 4 enables them torock or tilt in order to cooperate .with the several rolls 82, 83, 84,yet said-rolls are yieldingly supported so that they will yield in anupward, direction if necessary as the blades ass beneath them. As saidblades are pivotal y supported along one edge means are provided forengaging their opposite edges to hold them in correct position withrespect to the rolls. As here shown, the means to engage and lift orotherwise control the pos tion of the forward edges of the blades willnow be described.

Referrin to Figs. 6, 7 and 8, the bevelgear 101, w ich is secured to thespindle 98, and which is continuously rotated also meshes with abevel-pinion 110, secured to a shaft 111, and said shaft 111 bears amiter gear 112, which meshes with a miter-gear 114, secured to a shaft115, and said shaft 115 bears a miter-gear 116, which meshes with amiter-gear 117, secured to a shaft 118, and said shaft 118, bears agrooved pulley 120, over which a belt 121 passes, and said belt passesover a groovedpulley 122 secured to a shaft 124.

A. cam 126, is secured to the shaft 118,

v andv another cam 125, is secured to the shaft 124, and said cams arearranged to be successively engaged by the propeller-blades '94, whichpass over them, and-they act to lift the forward edges of said blades,thereby to pieces into firm engagement with said rolls and thereby tocause said body-pieces to a 5 move forward.

Referring to Fig. 6, it will be seen that the blades correspond in.shape and size to the body-pieces or thereabout, and said blades andcoiiperating-rolls act to move the body-pieces in the arc of a circle.Such movement continues until the body-pieces are moved into engagementwith the pastingmechanism.

The pasting-mechanism is designed to apply a lineof aste to one end onlyof the body-pieces, and for this to be done one end will be exposed, andreferring to Figs. 6 and 8 to 1,2, the forward edge of each blade 94 isarranged and timed to engage a bodypiece a short distance in rear of itsforward end, and to press it into engagement with the first roll 82 ofthe set, thereby leaving the end of the body-piece free, for a shortdistance, and the paste is subsequently ap- 5 plied to thisfree end ofthe body-piece.

When a body-piece is moved forward by a blade 94, coiiperating with theseveral rolls,

its free end will be en aged by the pastingmechanism. 'Said mec anism ashere shown. is of a rotating type, and comprises essen- A tially twocofiperating rolls 130, 132, usually conically formed. The upper roll130 is formed with a smooth face and is rotatablv mounted on ashaft 133,carried by a bloc 134, similar to the blocks 90, and similarly mounted,being yieldingly supported. .The under roll 132 is provided with alongitudinally extended rib 136,-by which the paste is applied to theexposed or free end of the see Fig. 9, and has a gear 137, secured to itwhich meshes with an intermediate ear 138, secured to a shaft bearinga-distri ut-. ing-roll 139, and said gear 138, meshes with a gear withina paste-receptacle 142. The paste: roll 141, is driven from the spindle98, by a belt 144, which passes over a pulley 145 on. the spindle, andover a pulley 146, on tlie journal of the roll 141, said belt alsopassmg over idlers 147 to give .it a quarter turn. The paste isdelivered by the paste-roll .141, to the distributing-roll 139, and bysaid roll 5 139 is deposited on the rib 136 of the applying-roll 132, assaid roll 132 rotates and its rib engages the distributingroll. .Thebody-piece is fed forward and the asting-rolls are timed with respect toe movement thereof, so that the rib 136 will engage the free end of theforwardly moving bodypiece and will apply a line fof paste thereto,after which said body-piece is fed forward by said pasting rolls to theforming'mandrel.

body-piece. The roll 132 is positively driven,-

140, secured to. a shaft bearing a paste-roll 141, which is journaled torotate 150 represents one of the mandrels, a large number of which areemployed, and said mandrels are extended radially from the periphery ofa circular rotatable mandrelsupport. Said support, as here shown, seeFigs. 1, 13 and 15, consists of a hub 151, bearing a plurality of radialspokes 152, to the extremities of which a circular rim 153, is secured,and the mandrels are arranged on the outside of said rim. The hub 151,is secured to the continuously rotating power-driven shaft 109, abovereferred to,

drel-support are moved continuously in a circular path, being revolvedabout the shaft 109, as an axis. Said shaft 109, is rotatedcontinuously, as. here shown, by a gear'154, see Fig. 1, secured to ;ashaft 155. which gear engages a large gear 108, secured to the shaft.109, and said shaft 155, has seso that the mandrels carried by the man--cured to it a pulley over which a drivingbelt 156 passes.

Each mandrel consists of a hollow frustoconical shell having a web 157,at each end, each web being disposed a short distance from the end ofthe shell, to provide a shallow recess at each end of the shell, 158representing the shallow recess at the outer end and 159, the wall ofthe shallow recess at the inner end. Each mandrel is secured to a hollowshaft 160, which extends through the rim 153 of the mandrel-support andterminates in a case 162, secured to'ithe frame-work of themandrel-support, said case having a'bearing 161 for the inner end ofsaid shaft 160. Each shaft 160 is rotatably supported in a sleeve 163,which extends through the rim 153, and said sleeve is rotatablysupported in a flanged bushing 164, arrangedin a hole in said rim 153,which is held therein by a threaded-collar arranged on its threadedend=portion," and-"bearing against theinner side of the rim.

As soon as the paste has be n applflifiskflr the body-piece 50, saidbody-piece is -con veyed to one of the mandrels, and it is here indesigned "that it" shall be engaged and held by suitable clamping-means.in engage- -mentwith the mandrel, said clampmgmeans engaging saidbody-piece slightly in rear of the line of paste, so ,that the pastedend-portion is free, and then to rotate the mandrel and clamping-meansto wind the body-piece around the mandrel and tocause its pastedend-portion to be overlapped by the opposite end-portion of thebody-piece; then to wipe the joint thus formed by suitable yieldingmeans, as a rag-wheel, which acts to remove any surplus'paste, and thento apply a suitable pressure upon the joint to insure adhesion of theend-portions. The

mechanism to accomplish these results will now be described.

Referring to Fig. 15, represents a clamping-arm, which is. made as anarrow Q movable radia y. support admits" of'the clamping-arm beingmovable in a direction radial to the axis of the mandrel, thereby .toengage the endportion of the body-piece and hold it in engagementwiththe mandrel,.and it is also I movable rotarily with the mandrelwhile 6 holding the body-piece in engagement therewith, in order thatthe body-piece may be wound around the mandrel, and it'is also movablerotarily a short distance, independ ently of the mandrel, to enable itto move 1 from a position adjacent the joint to a position above or uponthe joint to apply pressure to or upon the joint. The support for theclamping-arm, as here shown, consists of a-yoke 183 arranged in rear ofand atthe -m base of the mandrel, which embraces the hollow shaft160,(and has a stem 188 to which the inner end of the clamping-arm isattached, and has a projection 186, with or without a roll thereon forengagement with wa cam by which its position and the position of theclamping-arm borne by it is controlled. Said cam is her'e shown asformed- 'onthe interior of the wall or flange 159, at

- a the base of the mandrel, and is represented as comprising thecircular portion of the wall, having three notches or recesses 165,

166, 167. The support for the clamping-arm is arranged between guides184, 185, formed on the outerend of the sleeve 163, and is aamovablebetween said uides in a direction radial to the axis of t e shaft 160,and is held in continuous engagement with the cam by means of a spring181, the free end of which isarranged between pins 182 on the stem188,'and'its opposite end is attached to the interior of a circularflange, 180, arranged'on the outer end of the sleeve 163,

concentric with the axis thereof. Said sup-'- port being held betweenthe guides 184,185, on is movable rotarily with the sleeve on which saidguides are formed in addition to'being Rotary movement of the movedrotarily with 'andalso with respect to thereon to occupy differentpositions with respect to the cam, being movable from one to anothernotch thereof. 7

' For the purpose of rotating the clampingw member its sleeve 163 has agear 170 secured toit which engages a stationarily supported circularrack 171, and for the purpose of rotating the mandrel its shaft 160 hasa gear 172' secured to it which engages a stationthe mandrel andclamping-member are borne by the continuously rotating mandrel-supportit will be observed that by means'of said statio'narily supported rackssaid elements will be rotated. Said circular racks u the mandrel, andpermits the projection 186 arily supported circular rack 173, and, as-

are securedto a circular plate having a cen- -ter-hole for the shaft109, and preferably having a bearing for said shaft. Both circular racks171 and 173 are, however, mutilated, as will be hereinafter described,to

cause the gears 170 and 172 engaging them to control the. operation ofthe mandrel and the clamping-member in the following manner.

Normally the clamping-member-190 is in the dotted line position Fig. 17,with respect to the mandrel, its projection 186 entering the notch 165,and both said member and mandrel are rotating about their axes in thesame direction, and when in this position said member is removed fromthe mandrel a short distance. The mandrelsupport moves the mandrel andits clamping-member onward and when in the proper osition for thebody-piece to be projected between the clamping-member and mandrel thegear'172 on the mandrel-shaft will engage the blank place 174 on therack 173, thereby causing the mandrel to dwell, but the clamping-memberwill continue to move. As the clamping-member moves with respect to themandrel its projection 186' passes from the notch 165 onto the portionbe-; tween said notch andthe notch 166, as shown by full lines Fig. 17,and at this moment the end of the body-piece is projected between theclamping-member and the mandrel, as represented in 18. The

mandrel continues to dwell and the clamp- I ing-member continues to movewith re spect thereto until the projection 186 enters the notch 166,thereby permitting the v clamping-arm to move radially toward the'mandrel andtengage "the endof the bodypiece, as shown in Figs. 19 and20. At this moment the gear 172 again engages the rack 173and both themandrel and clampingmember are rotated about their axes while beingmoved rotarily by the mandrel-support and the body-piece is wound aboutthe mandrel. The mandrel and clamping-memher are thus rotated until thegear 172 on sleeve of the clamping-member, respectively, engage blankplaces 175 and 176 on the racks 173 and 171, and assoon as suchengagement is effected both the mandrel and its clamping-membercease torotate about their axes, although they continue to be moved rotarily bythe mandrel-support, as shown in Fig. 21. While dwelling'in thisposition means such as a rag-wheel is brought into op era- 120' the-1nandrel-shaft and the gear on the v t1on to. wipe the joint for thepurpose of removing. any surplus aste and to assist in adhesivelysecuringt t e ends together, such means being herea er described.

As soon as the rag-wheel has completed its operation the gear 170 on theclampingmember again engages its rack but the gear 172 on themandrel-shaft continues to engage a blank-place on its rack as themandrel-support continues to' rotate, and the clamping-member is againmoved with IR.- spect to the mandrel and its projection 186 disengagedfrom the notch 166 and moved into engagement with the notch 167 asrepresented in Figs. 22 and 23, such movement of the clamping-memberoperating to movethe clamping-arm out of engagement with the end of thebody-pieceand then into engagement therewith, but at a point abovetheljoint, see Fig. 23,fwhereu'po'n said clamp ing-arm acts to apply'apressureupon the joint, aiding in adhesively securing it. Then the gear170 again engages-ifthe blank-place 177 on its rack 171, and as the gear172 is still in engagement with the blank place 175,

both the mandrel and its clamping-member. will dwell while being movedrotarily by the mandrel-support. Such movement contmues until the 'gear170 again; engages its rack, and as the gear 172 still engages the blankplace 175 the clampingmember is again moved with ..respect to themandrel from theposition shbwii-ig. Fig. 22, to the dotted line positionshown "in Fig. 17, the

projection 186 disengaging the notch 167 and moving into engagement withthe notch 165; During such movement the clampingarm is moved away fromthe. joint so that anunobstructed space .is formed between it and thejoint. Then the gear-1 72 engages its rack 173 an'djboth gears beingthen in engagement with their racks, both .the mandrel and the.clamping-member will be rotated about their axes. Said rotating move".mentof theifmandrel' continues while the body-piece thereon is beingcoated with parafiin-wax or other suitable substance, and is cooled, andisfinally ejected from the mandrel, and at this time the mandrel-supporthas made approximately a complete cycle of its operation. The rag-wheelheretofore referred to will a now be described. This wheel, represented.at 200. in Figs' 1, 24 and 25, is of any usual or suitable construction,and is here shown as rotatably mounted at the upperend of alever 201,fulcrumed at 202,, and havingits lowerend arranged to press intoengagement with-a cam 203, by a spring 204. Said cam is secured to ashaft 205, adapted to be rotated by a belt 206- passing over a pulley onthe shaft 155. "The rag-wheel'200 is rotated by a belt 207 passing overan' idler 208 and around a pulley .210 on the shaft, 155.

mechanism, the rotat ng rag wheel is given- By means of this aperiodical oscillatory movement whereby:

one of its flat faces is moved along A the pasted joint to wipe 01f anysurplus paste, as represented in Fig. 25. As above stated the mandrel isdwelling during this time but being moved onward. by themandrel-support, and en%tgement of the rag-wheel with it is" for a sucient length of time to accom- Y plish the desired result. While themandrel+ support is rotating and'the gears 170 and 172 are in engagementwith theiblank-places 175 and 177, and said mandrel and its clamping.member are dwelling, the cupbodies on the mandrels are brought into p0-sition to receive circular bottom-pieces which areprojected into theopen ends of the cupbodies, the ends of said bodies projecting a shortdistance beyond'the ends of the m-andrel for this purpose. The means forforming such bottom-pieces and for inserting them in the cup-bodies willnow be described. Said circular bottom-pieces areformed from a widestrip of paper 220, see .Fig. 1, which is fed through a gu1de' 221 ontothe periphery of a circular punch-car;- rier-222, and beneath an endlessdie-carrying band which passes "over said carrier. The pimch-cgrrier isdesigned to carry a. series of radia ly-dispcsed punches,.and theband isdesigned to carry a series of dies,-and the.

dies and punches coact in such-manneras to cut circular bottom-piecesfrom the strip of paper which is fed betweenthemlike-unto' ordinarypunches and dies, except that the 1 operation is of a rotative characterand is continuous. As here shown, the circularcutting-punch-carriercomprises a rim 224,- see Figs. 28,29 and-'30, having two rows ofsprocket-teeth 225, 225, arranged in parallel,- p 105.

and adapted to enter interdental spaces formedin the edges'of the band226 which I carries the dies .227, see Figs. 26 and 27,-

thereby to enable said band to drive, rota'---2.

tively said carrier.- Said rim also has a ripheral groove 228, betweenits sprocketteeth to receive the strip of:pap er 220,- and I also thecutting-dies 227*.The clrcular-cuttmg-punch-carrier comprises a largecircular memberhaving a hub 229 and a smaller circular member-having ahub 230, andsaidmembers are bolted together and theirhubs arranged ina'linement and mounted rotata-.

bly on a stationarily supported :shaft 231,

The large member-229. which bears the rim 224 aforesaid, is providedwith a series of radially disposed guides 232,233, arranged inalinement, in which the punches-235 are arranged'to reciprocatelongitudinally andradially withrespect to the carrier. Eachcuttlng-punch 235 is encircled bya coiled spring 236, which bearsagainst the inner end of the guide 232,-andvagainst,a-

colla'r 237 secured tof'thepunch, the tendency of which is to retractthe punch or move it toward the center of the carrier:

is arranged between the hubs 229 and'230,

and is keyed to the shaft 231, and is, therefore, stationarilysupported, and the inner end of each punch ,may have a roll 238 thereonfor engagement with said cam-disk. The outer end of each punch is formedwith a cutting edge or portion which is shaped to coact with any of thedies 227, to cut .the bottom-pieces from the strip. The cut- ,ting'operation, however, is designed to take place at or about the time theband and cutting-punch-carrier meet, with the strip of paper betweenthem, and at this place a support for the die is arranged above it,which, ashere shown, comprises a yoke 242 supported on the shaft 231, ateach side of the cutting-punch carrier, the crown of which extendsacross the punch-carrier, near the rim thereof, and serves as anabutment against which the die is pressed while the punch isoperated;The cam-disk 239 is represented in Fig. 29, as having a singleprojection arranged at a point, opposite the crown of the yoke, and asthe punch-carrier is rotated by the die-carrying band the punches willbe successively moved outward while passing over said projection, tocoact with a die and cut the paper, and will be immediately thereaftercaused to resume their normal positions by their retractile springs.

The cutting-punch-carrier is arranged close to therotatingmandrel-support, and

its driving die-carrying band derives its motion from said support so asto work harmoniously therewith, and, as here shown, said mandrel-supporthas on its rim 153, segment-gears 191, 192, see Figs. 13 and 14, whichare spaced apartso as to engage the interdental spaces-in the oppositeedges of the die-carrying band 226, thereby to drive said band. Saidsegment-gears are also sep arated to enable theblades 94 of therotatable propeller to pass between them.

The cutting-punch-carrier is adjustably supported to admit of tighteningthe .diecarrying band, and, as here shown, its shaft 231 is mounted atits ends in blocks 243, see Fig. 30, which are slidable in slots 244,formed in arms 245, loosely mounted on a shaft 246. Said blocks. 243 areadjustable in said slots by screws 247. The shaft 231 is also adjustablysecured by nuts in arcuate slots 248, formed in the o-uter ends ofarms250, which are loosely mounted on bosses on the stationary frame bearingthe circular racks 171, 173, or it may be, otherwise supported. The yoke242 is connected with the arms 245 by rods having turn-buckles 251,thereby to hold the yoke in fixed position yet admit of its adjustmentso as to correctly locate it with respect to the die and punch which isbeing operated. The bot comprises strip of paper'will remain in the diesand will be carried along by the endless diecarrying band to thebottoming-device Assuming the bottom-pieces are cut at the I top of thepunch-carrier, as here shown, the waste strip from which thebottom-pieces have been cut is taken from the bottom of the carrier, seeFig. l, and said waste strip may be (passed through a slot 254, in thelower en of the guide-plate 221 to conduct it away from the machine. Thebottomingdevice by which the bottoming-pieces ,are formed with flangesand are thrust into the ends of the cup-bodies, is constructed similarin many respects to the bottom-piece cutting-device just described, andis shown particularly in Figs. 1, and 31 to 35, and a rotatableplungercarrier around which the aforesaid endless die-carrying bandwpasses, and which is rotated by said band, and hence in unison with thebottom-piece cutting-device.

The rotatable plunger-carrier is located near the rotatablepunch-carrier and along the space between said'carriers the endlessdie-carryin'gvband continuously engages the mandrel-support, wherebymotion is imparted to it, and during such engagement with themandrel-support the open ends of the cup-bodies are brought intoengagement with the dies borne by the die-carrying band preparatory tohaving bottom-pieces thrust thereinto. As here shown, said dies 227 arearranged to act as cutting and also as forming dies, and have twocircular recesses 255, 256, the recesses 255 being arranged on theinside and the recesses 256 being arranged on the outside of the dies,there being annular projections 257, between said recesses. Thebottom-pieces, when cut, consist of flat circular disks, which enter andare retained in the recesses 255. As the endless band engages the gearon the mandrel-support the projecting ends of the cup-bodies enter therecesses 256, as represented in Fig. 31, and the bottom-pieces arethrust through the dies into the open ends of-the cup-bodies while saidcup-bodies are thus held. As the bottom pieces are thrust through thedies'the edgesthereof are upturned by pass-. ing over the annularprojections 257, form ing flanges thereon, so that preparatory to beinginserted in the cup-bodies they are flanged and when inserted thereinthe flanges engage the cup-bodies. The bottom-pieces are thrust throughthe dies by the plungers carried by the plunger-carrier.

Said "plunger-carrier is designed to carry a series of plungers, whichare movable longi-.

tudinally and radially with respect to the CiLI'I'leI'. Referring toFig. 31, the plunger-carrier 'is made circular, and comprises arim 260,

having two rows of sprocket-teeth 261,261,
